in which certain embodig vention v.has been applied. lIt is, of course, obvious that the lnovel 'spring vandmsh'ocl; abf' sorbing elements constructed accordingt the principles' of5 my invention" may 'bey applied to any type of vehicle, whether self-propelled' 55 or not. Theillustrationsin the drawings and' the descriptionsherein are merely exemplary, and variousmodifications may be made therein without departing. from the scope of `the,

invention as defined by the subjoined claims.60

The front axle ofthe'vehicle illustrated in vthe drawings is shown at -11 andfhas pivoted thereto,n as at l2, the front vvheell` Any suitable or preferredform of steering mecha-j nismmay lbe provided'in this connection.` 65

v The rear`v axle 15 vsupportedV bythe driving f wheels, one of which is shown at 16,-is en# Y vAs. shown in Figure 5, the usual brake drum 18 is pro-I vided, togetherfw'ith thefinner brake. drum.7.0.x H

casingl).l v A. 1 In lieu Aoffthe usual front and rear leaf o f springs, therev is provided,in the present cons struction, the elements 20, one-being disposed at each end of the channel sdebeamsflO, the (5 forward members 20 being secured t0 the f frontendofthegbeams l0, as'V atQl, and the rear' members' being secured yto thev lugs 22,V

ywhich Adepend from` the'rear portions" of. the

beams 10. The rear ends of each ofthe memf 8.0i

'bers`20 are secured tothe beams 10 as jat-23 and 24: respectively.t 'ThesemembersQO'are not designed to support the weightofthe ve. hicle but merely serve as means for maintainf ing theaxles in longitudinally 'and laterally 85 sp-aced'relation with they chassis of the vehicle. For this purpose aheavy constructionis not required, and each oft-bese' elements may be formed of aband of steel 'approximating the "size andshape of a single leaf fofthefrf'leaf' '99 At, v their approximate mid-points these strips 2O f spring usually provided atlthese points;

aresecuredtothe axle 111 as l,s hown'at'25 and tothe rearv axle housing asfshow'n at 26'.

l' A modifiedfor'm of connection is shown in Figure?, vinf which the member 20 extends onlybet-ween the lug 22 and the point 26. a i

' My improved spring deviceswhilefollow ingthe same general lines of construction, are subj ectgto 'slight modifications according., to En whether they are to be used in connection with the front axle or the rear axle housing of the vehicle. In the case of the front members, shown to best advantage in Figures 2 and 3 of the drawings, there is provided a substantially .L -shaped bracket 30, the lower horizontal portion 31 of which is secured to the top of the axle 11 by means of the bolts or other securing elements 32. 1t will be noted'that the spacing members are clamped between the bracket portion 31 and the. top surface of the axle, as clearly shown in vFigure-2. A' brace 34, which is preferably ll-shaped in cross-section, extends between the'brac-ket portion 33 andthe upwardly bent outer end 350i the front axle 11. The lower end ofthe brace34is biturcated and isV secured to thev axle as at 36.- Flanges 37 'are providedatthe upper jend of the brace 34 and are bolted vor eral shape as the front brackets and are otherwise secured to the upper portion 33v of provided with `the horizontal portions 31 `which are curved as at 38'to tit the, rear axle housing 17.v A complementary clamping member. 39 is itted to the underside ot the housingl'? and'secured to the portion 31" by Y. means of bolts or any other vsuitable lfastening elements which are adapted to connect the` adjacent anges 40 off the members 31 and 39. A The rear members 2O may be secured to these clamping members 39 by means of rivets l 32 or any, other desired means, or they may be suitably secured to the axle housing 17 itself. Instead of a brace, such -as themember l34`provided in connection with the front bracket, the substantially vertical. portions of -1- the rear brackets 30 are shaped to the contourvof the inner surface of the brake drumI v casing 19 andare secured thereto' by'ineans ears 42.

of, 'the bolts '41.'. In practically all other respects the front and rear brackets 30 and 31 f are similarly constructed, and this common -145 construction will new be described., Y

l,Upon each 'side ofthe upstanding portions Yot the brackets 30a-nd 30, at the lower ends thereof, are provided the inwardly directed The upper outwardly bent portions 33 of thcbrackets are provided with the upstanding spaced ears 43.

A pair of brackets is secured to the body portion oi' the beam 10 by means of suitable fastening elements 46. The brackets 45 are provided with horizontal flanges 47 which are adapted to underlie the bottom anges of the channel 10 and to be secured thereto by the fastening means 48.V Spaced outwardlydirected langesf49 are formed upon the ,ce

brackets 45 and are each adapted to be disposed in transverse 'alignment with 4one of the ears and 43. `Each ot the ears 42 and 43 Vandthe upper and lower portions of each yof the vflanges 490i the brackets 45 are provided with perforations through which are ,aremadein the'form of loops and are adapted to connect the pins 50 which extend between the upper ears 43 and between the upper portions of the brackets 45., rlhese straps or loops are preferably built up kof concen? tric'layers of she-et rubber to' form 'a'sjtrongmultiple ply or (laminated structure.- The.. layers 56 may be continuous, having their ends secured to-prevent unwinding, Vvor they may be formed of a plurality ot separate individual loops graduated in'siZefir-om the inner surface of the straps 55 yto the outer'surrl-` face thereof, as in the preterredlembodiment illustrated inthe drawings. Y f

As a means orchecking the rebound of the vehicle, the pins 50connecting the lower ears 42 and the lower -portions'of the Yflanges 49 of the bracket 45 are connected byila similar loop or band 60 which isi-of thesame con-` struction as the bands'55 ibut whichy may be formed of fewery laminations since Vit will not have to "withstand as great shocks as" the bands 55 whichserve to' support thewweight of the vehicle romthe-"brackets 'l 'z It will be apparent from the foregoing description and the accompanying illustrations that there is provided, bymcans of the present invention, an extremely eiiicient spring vsuspension and shock*absorber*or-rebound if;

lirmly secured and braced 4in their respective axles and housings, 4and .theimembers 20 Vcooperate with the resilient suspensionnrto pre# vent undue lateral and longitudinal: sway of the chassis' with respect tothe support-ing Having thus described the inventiomwhat Letters Patent is: f

end of the rear axle housing of a vehicle and secured at an intermediate portion to the brake drum housing, an elastic supporting element connecting the upper end of said bracket with the chassis of the vehicle, vand an elastic rebound checking vmember connecting said chassis to the lowerend of said bracket.

5. In a combined vehicle spring and shock absorber, in combination, an upstanding bracket mounted on the axle of a vehicle, a

bracket secured to the chassis of the vehicle and normally disposed adjacent to and intermediate the ends of said rst named bracket, a rubber strap connecting said second named bracket with the upper end of said iirst named bracket, andv a second rubber strap connecting said second named bracket withV the lower portion of said rst named bracket.`

6. In a combined vehicle spring suspension s and shock absorber, in combination, an upstanding bracket mounted upon an axle of said vehicle and provided with a pair of lugs at the top and bottom ends thereof, a sleeved pin connecting the; lugs of each pair, a pair of brackets adapted to be secured to the channel beams of the chassis of said vehicle,`
